Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to a clamping device for PVD coating spraying. Background Art
[0002] Physical vapor deposition technology refers to the technology of using physical methods under vacuum conditions to vaporize the surface of the material source (solid or liquid) into gaseous atoms or molecules, or partially ionize it into ions, and deposit a thin film with certain special functions on the surface of the substrate through a low-pressure gas (or plasma) process. Physical vapor deposition is one of the main surface treatment technologies, which can achieve the purpose of coating spraying construction at room temperature.
[0003] During coating, a clamping device is required to clamp and lock the substrate. Traditional clamps lock the substrate by clamping the limit from the side. Part of the locked contact position will be blocked, affecting the uniform adhesion of the coating. In addition, each time the substrate is replaced, the clamp needs to be opened, the substrate is placed in, and then the clamp is closed, making it inconvenient to operate and difficult to position when replacing the substrate. Therefore, we propose a clamping device for PVD coating spraying. Utility Model Content
[0004] The purpose of the utility model is to provide a clamping device for PVD coating spraying. By arranging rubber rollers that can be driven by an electric push rod to approach or separate from each other, the rubber rollers can be driven close to each other and can just clamp and lock the substrate. When the rubber rollers are tightly locked, the substrate can be locked. Each time the substrate is replaced, it is only necessary to release the lock on the rubber roller, so that the substrate can be quickly pulled out and replaced. The positioning of the substrate is faster, making replacement more convenient, thereby solving the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping device for PVD coating spraying, comprising a bottom plate and a vertical plate, wherein two vertical plates are provided, and the two vertical plates are vertically fixed on both sides of the surface of the bottom plate; electric push rods are horizontally installed on the front and rear surfaces of the outer sides of the vertical plates, and the ends of the electric push rods penetrate into the inner sides of the vertical plates, and a push plate is fixed to the ends of the electric push rods, and a rotatable rubber roller is installed on the inner surface of the push plate; an iron plate is vertically arranged on the side of the rubber roller close to the push plate, and connecting rods are horizontally fixed on the upper and lower sides of the iron plate away from the rubber roller, and the connecting rods can slide through the other side of the push plate, and a limit plate that abuts against the surface of the push plate is fixed to the ends of the connecting rods, a spring is sleeved on the outer ring of the connecting rod between the push plate and the iron plate, and an electromagnet is installed on the surface of the push plate close to the iron plate.
[0006] By adopting the above technical solution, the bottom plate fixes the entire device, and the distance between the rubber rollers on both sides of the front and rear ends is adjusted first so that they can just clamp and lock the substrate. When the rubber rollers are unlocked, the substrate can be quickly and conveniently pulled out, and the new substrate can be quickly positioned and inserted. The rubber rollers can be locked again to quickly lock the substrate.
[0007] Optionally, a through rod hole is opened on the surface of the push plate, and the connecting rod passes through the push plate through the rod hole.
[0008] By adopting the above technical solution, the connecting rod can slidably penetrate the push plate through the rod hole on the surface of the push plate.
[0009] Optionally, a conical groove is formed around the outer ring of the rubber roller, and the depth of the middle part of the conical groove is greater than the depth of the two sides thereof.
[0010] By adopting the above technical solution, the substrate can be placed horizontally in the conical groove on the surface of the rubber roller to be locked by contact, thereby achieving clamping and locking of the substrate and ensuring that the side edge of the substrate is not blocked.
[0011] Optionally, a rubber pad is fixedly attached to the surface of the iron plate, and the iron plate contacts the surface of the rubber roller through the rubber pad.
[0012] By adopting the above technical solution, the iron plate is pressed against the surface of the rubber roller through the rubber pad, thereby ensuring the locking effect of the rubber roller.
[0013] Optionally, the rubber rollers on both sides of the bottom plate surface have the same height and the same size.
[0014] By adopting the above technical solution, it can be ensured that the substrate is supported horizontally.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] 1. The technical solution of the present application is to set up rubber rollers that can be driven by an electric push rod to move closer to or away from each other. The rubber rollers can be driven close to each other to clamp and lock the substrate. When the rubber rollers are tightly locked, the substrate can be locked. Each time the substrate is replaced, it is only necessary to unlock the rubber rollers, so that the substrate can be quickly pulled out and replaced. The positioning of the substrate is faster, making replacement more convenient.
[0017] 2. The technical solution of the present application uses a spring to push the iron plate to make the rubber pad press against the surface of the rubber roller to quickly lock the rubber roller. The electromagnet adsorbs the iron plate to separate the rubber pad on its surface from the surface of the rubber roller, thereby quickly releasing the lock on the rubber roller.

[0022] See also Figure 1-2 The utility model provides a technical solution: a clamping device for PVD coating spraying, comprising a bottom plate 1 and a vertical plate 2, wherein two vertical plates 2 are provided, and the two vertical plates 2 are vertically fixed on both sides of the surface of the bottom plate 1, and the vertical plates 2 on both sides are arranged parallel to each other.
[0023] Electric push rods 3 are installed horizontally on the front and rear surfaces of the outer side of the vertical plate 2. The ends of the electric push rods 3 penetrate into the inner side of the vertical plate 2, and a push plate 4 is fixed to the end of the electric push rods 3. All the push plates 4 have the same height, and the push plates 4 on the left and right sides are parallel to each other. A rotatable rubber roller 41 is installed on the inner surface of the push plate 4. The rubber rollers 41 on both sides have the same height and the same size. A conical groove 411 is opened around the outer circle of the rubber roller 41. The substrate is placed horizontally between the rubber rollers 41 on the left and right sides and aligned with the conical groove 411. Then the rubber roller 41 is driven to approach the two sides of the substrate so that the side edges of the substrate hit the conical groove 411. The middle depth of the conical groove 411 is greater than the depth on both sides. The side edges of the substrate hit the area with a large depth in the middle position to achieve clamping of the substrate.
[0024] An iron plate 5 is vertically arranged on the side of the rubber roller 41 close to the push plate 4, and the iron plate 5 is arranged parallel to the push plate 4. Connecting rods 52 are horizontally fixed on the upper and lower sides of the iron plate 5 away from the rubber roller 41. The connecting rod 52 can slidably penetrate to the other side of the push plate 4 through the rod hole 42 opened on the surface of the push plate 4, and a limiting plate 522 is fixed at the end of the connecting rod 52. The diameter of the limiting plate 522 is larger than the inner diameter of the rod hole 42, and the limiting plate 522 is in contact with the surface of the push plate 4. A spring 521 is sleeved on the outer ring of the connecting rod 52 between the push plate 4 and the iron plate 5, and the two ends of the spring 521 are respectively in contact with the surfaces of the push plate 4 and the iron plate 5, so that the iron plate 5 can be contacted to the surface of the rubber roller 41, and the rubber pad 51 fixed on the surface of the iron plate 5 is in contact with the side surface of the rubber roller 41, locking the rubber roller 41 so that it cannot rotate, thereby realizing the locking of the substrate.
[0025] An electromagnet 43 is installed on the surface of the push plate 4 close to the iron plate 5. When it is necessary to pull out the substrate and replace it with a new one, the electromagnet 43 is energized to adsorb the iron plate 5, forcing the rubber pad 51 to no longer contact the surface of the rubber roller 41. The rubber roller 41 can rotate freely to facilitate the substrate to be taken out or imported.
[0026] When in use, the device is stably supported and fixed in the PVD coating construction equipment by using the base plate 1, and then the electric push rod 3 and the electromagnet 43 are connected to the control device and energized, and the substrate is placed horizontally between the rubber rollers 41 on the front and rear ends, and the two sides of the substrate are aligned with the conical grooves 411 in the middle of the rubber rollers 41 on both sides, and then the electric push rod 3 is controlled to drive the rubber rollers 41 on both sides to approach the substrate, and the two sides of the substrate can just contact the inner surface of the conical groove 411 to achieve clamping and locking of the substrate, and then the PVD construction equipment can be made to work and the PVD coating can be constructed. After the coating is attached to the surface of the substrate, the electromagnet 43 is energized to adsorb the iron plate 5, and the iron plate 5 is adsorbed close to the push plate 4 and its surface The rubber pad 51 on the surface no longer contacts the surface of the rubber roller 41, and the locking of the rubber roller 41 is released. After that, the substrate can be pulled to rotate the rubber roller 41, which is convenient for pulling out the substrate. After that, the two sides of the new substrate to be coated are aligned with the conical groove 411 of the rubber roller 41, and the substrate is pushed between the two rubber rollers 41. Under the rolling and guiding action of the rubber roller 41, the substrate is inserted into and contacts between the rubber rollers 41 on the front and rear ends. At this time, the electromagnet 43 is powered off and loses its magnetism. The electromagnet 43 no longer adsorbs the iron plate 5. Under the action of the spring 521 for resetting, the rubber pad 51 on the surface of the iron plate 5 will be pressed against the surface of the rubber roller 41 again, locking it, thereby achieving locking of the substrate.
